To ensure years of precise performance, maintain this product periodically based on the frequency of use.
Read the maintenance precautions thoroughly before maintaining this product.

Maintenance Precautions

• This machine includes parts that must be replaced periodically. We, therefore, recommend taking out a maintenance contract. Clean this machine and replace consumable items to prevent quality defects and accidents.

warning

• Clean periodically. Debris and dust will accumulate on electrical components when this machine is used for extended periods. There is a risk of failure, electric shock, or fire due to current leakage.

• Do not clean by blowing—e.g., avoid using air blowers. Doing so may lead to failure, electric shock, or fire involving the machine if airborne debris or dust gets inside electrical components.
  Wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out. A vacuum cleaner may also be used for cleaning.

• Do not allow liquids to get inside the product. Otherwise, there is a risk of failure, electric shock, or fire.

caution

• The UV-LED unit becomes extremely hot. Do not touch the unit until it cools down after turning off the LED.
• For heavy soiling, wipe using a soft cloth soaked in dilute detergent and thoroughly wrung out.
• Pay close attention to ventilation and be sure to wear safety glasses, gloves, and a mask when handling ink, maintenance liquid, waste ink, or other solutions used with this machine. Leaking ink may adhere to the skin or get into the eyes or mouth.

notice

• Never touch the print head nozzle surface. Do not allow water or alcohol to come into contact with the print nozzle surface. This will increase the risk of machine failure or printing defects (e.g., nozzle clogging or deflection).
• Do not use cotton swabs to clean around the head or carriage. Fibers from cotton swabs may adhere to the head nozzle surface and lead to printing defects (e.g., nozzle clogging or deflection).
• Be careful to avoid splashing ink or maintenance liquid on the covers. Exposure to splashing ink or maintenance liquid may damage or deform the cover.
• Do not use benzine, thinner, or any chemical agent containing abrasives. Use of these chemicals may result in damage to or deformation of parts.
• Do not move the carriage by hand. To move the carriage, use the carriage out function on the menu.

Avoid storing this product in locations accessible to children.

Performing Maintenance

Ink Maintenance
If ink constituents are sedimented, the ink density may become uneven. We recommend shaking the Ink bottle periodically to keep printing consistent.

• UV ink: once a month.
• White ink: once a day.

Shake the Ink bottle

Shake the Ink bottle to the left and right slowly at least 20 times.

• Tighten the ink bottle lid securely, then shake the bottle slowly from left to right to ensure that the ink moves inside, holding the ink bottle lid with a paper towel.
• Shake slowly. If the bottle is shaken too violently, ink may leak out or the air mixed in the ink may cause nozzle clogging.
• If the ink bottle is partially used, tilt it slowly until the ink bottle is upright.

Wiper Cleaning

The wiper wipes off ink adhering to the print head nozzle surface. Continuing to use the dirty wiper may cause the wiper to which dried ink and dust are attached to rub against the nozzle surface, leading to printing defects
(e.g., nozzle clogging or deflection).

Be careful to avoid leaving fragments from the cleaning stick behind when cleaning. These fragments will increase the risk of printing defects (e.g., nozzle clogging or deflection).

1. From MENU on the touch panel, touch [MAINTENANCE].
   The Maintenance menu is displayed.

2. Touch [Daily maintenance] > [Daily station maintenance].
   The carriage moves over the table.
